well I have a Turbotrix 50trim turbokit on mine it is capible of 415 on just 93 and 500 on race gas. Ill tell you that on pump only the car is scary fast. I raced a supercharged new stang GT at the track and completely killed it. As for your brakes mine are noisy to but I have hawk ceramic pads so they will not sure what you got.

 

Thats cool. I swear I hate the stock exhaust , speacily the downpipe and its heatsheilds. Mine are all rotted around the exhaust bands/clamps. I just ripped them off . So much quiter now . I wish i had the money so i could just do my turbo back exhaust.
